Updated November 2026. You need a valid Energy Performance Certificate (EPC) to market and let a home in England and Wales, and the minimum rating is set to rise from band E to the equivalent of band C by 1 October 2030. This guide covers what you must do now, what is changing, and how to plan the upgrades without overspending.
EPC requirements for rental properties come from two sets of rules. The Energy Performance of Buildings (England and Wales) Regulations 2012 say you must have an EPC and give it to tenants. The Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015, known as MEES, set the minimum rating you can let at. Scotland has its own regime.
Key takeaways
- You need a valid EPC before you market the property, and the tenant must get a free copy.
- An EPC lasts 10 years. The current legal minimum for letting is band E, unless you register an exemption.
- The Government has confirmed a single deadline of 1 October 2030 for all private tenancies to meet the equivalent of EPC C, measured on new EPC metrics.
- You will not have to spend more than £10,000 per property (or 10% of its value if it is worth under £100,000). Qualifying spending from 1 October 2025 counts.
- The 2030 rules are confirmed policy, but the regulations still have to be made, so details can change.
What is an EPC?
An Energy Performance Certificate rates a home’s energy efficiency from A (most efficient) to G, with a score out of 100, and lists recommended improvements with rough costs. It is produced by an accredited domestic energy assessor after a visit, usually costs well under £150, and is lodged on the national register. You can check any property’s certificate on GOV.UK’s find an energy certificate service.
EPC requirements for rental properties today
- Before marketing: you need a valid EPC (or to have commissioned one) when you advertise the property, and the rating should appear in adverts.
- Give it to the tenant: prospective tenants must get a free copy, at the latest before the tenancy is agreed.
- Validity: 10 years. You do not need a new one just because a tenancy renews, as explained in our guide to EPCs on tenancy renewal. You do need one if it has expired and you start a new let.
- Minimum rating: since April 2020, you cannot continue to let, or start a new let of, a property rated F or G unless a valid exemption is on the PRS Exemptions Register.
Some buildings are outside the rules, including certain listed buildings where the required works would unacceptably alter their character, and holiday lets that are not let on a tenancy. Check the GOV.UK MEES landlord guidance before assuming an exemption applies.
Current exemptions and the £3,500 cap
If a property is F or G, you must make the recommended improvements up to a cost cap of £3,500 including VAT. If it still falls short, you can register a high-cost exemption. Other exemptions cover cases where all relevant improvements are done, where wall insulation would harm the building, where consent from a tenant, lender or freeholder is refused, where works would cut the value by more than 5%, and a six-month exemption when you have just become a landlord. Most last five years and must be registered before you rely on them.
Penalties
Councils enforce MEES. Letting a substandard property can mean a civil penalty of up to £5,000 per property under the current rules, and the Government intends to raise the maximum to £30,000 alongside the 2030 standard. Failing to provide an EPC is a separate breach with its own fixed penalty.
The big change: EPC C by 1 October 2030
On 21 January 2026, alongside the Warm Homes Plan, the Government published its response to the consultation on improving the energy performance of privately rented homes. The confirmed policy for England and Wales:
The road to EPC C for rented homes
Band E minimum, £3,500 cap
Qualifying spend starts counting to the £10k cap
Last chance for a current-style C rating to count
All tenancies at EPC C equivalent, or exempt
- One deadline: 1 October 2030 for new and existing tenancies alike. There is no earlier date for new lets.
- New metrics: compliance will be measured on reformed EPCs. A property must meet a fabric performance standard plus either a heating system or a smart readiness standard.
- Grandfathering: a property rated C or above on the current Energy Efficiency Rating, on an EPC issued before 1 October 2029, will be treated as compliant until that EPC expires or is replaced.
- Cost cap: £10,000 per property, or 10% of its value if worth under £100,000. Reasonable EPC and retrofit advice costs count towards it. If the property still falls short after spending up to the cap, a cost-cap exemption lasts 10 years.
- Expected spend: the Government’s impact assessment estimates an average of around £5,400 per property that needs work.
Today’s rules versus 2030
| Current rules | From 1 October 2030 (confirmed policy) | |
|---|---|---|
| Minimum standard | Band E | EPC C equivalent on new metrics |
| Cost cap | £3,500 incl. VAT | £10,000 (or 10% of value under £100k) |
| Spending that counts | Recommended works | Qualifying works from 1 Oct 2025, plus EPC and advice costs |
| High-cost exemption length | 5 years | 10 years |
| Maximum penalty | £5,000 per property | £30,000 proposed |
How to plan your upgrades
- Check your current certificate. If it is C or above and issued before 1 October 2029, you may already be covered until it expires.
- Read the recommendations. Loft and cavity wall insulation, heating controls and low-energy lighting are usually the cheapest points per pound.
- Start with the fabric. The new standard puts fabric performance first, so insulation and draught-proofing matter more than before. The table below sets out the usual options in order.
- Time the works around voids. Disruptive jobs are easier between tenancies.
- Keep every invoice. You will need them to prove spending towards the cap and to support any exemption.
- Look for funding. Heat pumps can attract a Boiler Upgrade Scheme grant; see our heat pump guide for landlords.
Upgrades that usually move the rating
Your EPC’s recommendations section lists the measures the assessor modelled for your property, with an indicative cost and the rating you would reach. Use that as your starting list. In most homes the order of value looks like this:
| Measure | Typical disruption | Why it matters |
|---|---|---|
| Loft insulation (top-up to around 270mm) | Low: a day, tenant can stay | Often the cheapest fabric gain |
| Cavity wall insulation | Low: injected from outside | Large fabric gain where cavities are unfilled |
| Draught-proofing, hot water cylinder jacket, pipe lagging | Very low | Small gains for very little cost |
| Heating controls (programmer, room thermostat, TRVs) | Low | Helps the heating system metric |
| Low-energy lighting | Very low | Small but quick |
| Boiler replacement or heat pump | Medium: best between tenancies | Big change to running costs; heat pumps may get a grant |
| Double or secondary glazing | Medium | Modest rating gain for the cost |
| Solid wall or floor insulation | High: usually needs a void | Big gain in older homes, but expensive |
Get a fresh EPC after the works, or a pre-assessment before you commit to expensive ones, so you know the rating you will actually achieve. The government has also proposed a separate exemption for landlords who prefer not to install solid wall insulation. The new rules still need legislation, which the government intends to bring into force in 2027, so check the GOV.UK MEES guidance before large spending decisions.

Common mistakes
- Letting an EPC expire between tenancies and re-marketing without a new one.
- Assuming an exemption applies without registering it on the PRS Exemptions Register.
- Spending on expensive measures first when cheaper fabric improvements would lift the rating further.
- Waiting until 2030. Installers and assessors will be busiest as the deadline nears.
Frequently asked questions
What EPC rating do I need to let a property?
At least band E today. From 1 October 2030 the minimum is due to rise to the equivalent of band C for all private tenancies in England and Wales.
How much will I have to spend to reach EPC C?
No more than £10,000 per property, or 10% of its value if it is worth under £100,000. If it still falls short, you can register a 10-year exemption.
How long is an EPC valid?
Ten years. You need a valid one whenever you market the property or start a new tenancy.
Does an existing EPC C still count after 2030?
Yes, if it was issued before 1 October 2029 and shows C or above on the current rating. It counts until it expires or is replaced.
Do holiday lets need to meet EPC C?
Short-term holiday lets are not covered by the 2030 private rented standard, although an EPC may still be needed when you market or sell.
